Two of Ireland's leading Islamic organisations say they have notified Gardaí about a website that promotes large scale migration of Muslims to settle in Ireland.
The Islamic Cultural Centre and the Islamic Foundation of Ireland are threatening legal action unless photos of the centre are removed from the "Hijira to Ireland" website.
In a joint statement, they say the project does not serve the interests of Muslims in Ireland and may create hostility and resentment against them.
They have already had the contact names and numbers of senior members of their staff removed from the site.
A statement from both organisations said: "Forensic investigation has been carried out of both domains and the information has been passed on to the Gardaí who are now investigating the matter. We disassociate ourselves from the project and affirm that the people behind this and their place of residence are not known to us.
"Although after showing our objection to the matter above, through their Facebook page, we have managed to get our names and contact details removed, however, photos of our Centre still remain on their website. We have demanded the removal of such photos an informed them that we will be taking a legal action if this is not done.
"We believe the approach taken by this project will not be serving the interests of the Muslims of Ireland who enjoy peace and security in this beautiful country but instead might create hostility and resentment against them."
